SPINDLE A.ND BEARING.

SPECIFICATION forming part of Letters Patent No. 718,349, dated January 13, 1903.

Application filed December 28, 1901. Serial No. 87,587. (No model.)

To all whom t may concern: threaded tou'eceive a nut b,-Which holds the i Be it known that I, GEORGE HILL, a citizen support upon the rail.

In the construction shown the invention, vsuch as will enable others in Figs. 2, 4, and 5 the support B has an oil- 6o ro skilled in the art to which it appertains to passage c', which intersects the circular cavmake and use the same, reference being had ity or recess and leads the oil to the chamber to the accompanying drawings, and to letters B', the oil-passage being enlarged at its outer of reference marked thereon, which form a end to provide an oil-cup, which may be part of this specification. closed by a suitable cover.

The spindleings upon which the Whirl rotates, the concarrying whirl D at its upper end has a ta- 7o zo struction of the part-s being` such that the .pered recess or opening in which is secured spindle is carried by the whirl and is mainthe tapered butt of the spindle, and said tained out of engagement with the bolster Whirl has the usual cup and pulley.

The upper support constructed in accordance with my -portion of the bolster carries an adjustable invention.

The oil-chamber maybe In the drawings, A indicates a part of the filled through the passage c' and by capillary frame or rail of a spinning-machine which attraction is fed to the ball-bearings. l Any has openings which receive the support or surplus oil flows into the recess in the casting casting B, the same having a hollow depend- B and is fed therefrom back into the chamreo 5o ing portion which extends through the openber.

ings in the rail, said part being externally When it is desired to separate the parts for adjusting or cleaning, the set-screw is disengaged from the sleeve. The whirl may then be raised from the sleeve to expose the bearings. The bolster can be separated from its support when it is desirable to have access to the oil-chamber. In the construction shown in Figs. 2, 4, and 5 the device is more particularly intended for the automatic supply of light lubricating-oils, and the construction is such that in practice there can be no gyra tory mot-ion given to the spindle.

The construction shown in Fig. 3 provides for the manual feed of a heavy lubricant, as grease. A hollow bolster is used,the ball-raceways of the bolster being integral, and through such bolster are apertures through which the grease is forced upon the bearings. The bearings carried by the whirl are in separate pieces, the lower one being adjustably secured in place and locked by a screw. The opening through the part B is adapted to receive a sleeve with which the hollow bolster is connected, said sleeve being internally threaded to receive a piston or follower I, which can be turned to force the `grease from the chamber 1:3/ through the openings upon the bearings. The sleeve or cylinder extends beyond the depending portion of the part B and is threaded to receive a nut 7L. The upper end of the bolster has a threaded stem, over which is placed a washer, which retains the upper set of balls, the washer being held in place by a nut (Z. To remove the whirl and bolster from the part B, the nut 7L is taken off and the sleeve is withdrawn. The lower bearing maybe then taken of and the bolster Separated from the whirl.

It will be seen that in the practical embodiment of my invention I can by slight ineditication ol' the parts use either a light or heavy lubricant and that many of the parts are common to both forms of the invention.

I clainil. A spindle bearing and support comprising a part having a chamber for a lubricant, a hollow bolster with bearings, the bolster being removably connected to the part having the chamber, a whirl to the upper end of which the spindle is attached, bearings carried within the balls interposed between the bolster and bearings and means for taking the lubricant from the oil-chamber through the bolsier to the bearings, substantially as shown.

2. rl"he combination in a spindle and bearing, oiI a whirl having bearings and a pulley with converging faces on the outside between the bearings, a hollow bolster with bearings, balls between the bearings of the whirl and bolster, a chamber for the reception of lubrieating material, the bolster being connected to such chamber, and means for supplying lubearings, and means for supplying the lubrii cant from the chamber to the aforesaid bearings, substantially as shown.

4. In a spindle-support, the combination of a support having an oil-chamber and a recess above said chamber, an oil-passage from the exterior of the support to the oil-chamber said passage being in communication with the recess, a hollow bolster attached to the support, a whirl mounted on the bolster, and a wick for carrying the oil from the oil-cham ber to the bearings between the bolster and whirl, substantially as shown.

5. In a spindle-support, the combination of asupport whichisdetachably connected to the frame or rail of a spinning-machine, an oilchamber in said detachable support, a hollow bolster attached to the support and provided with a fixed and with an adjustable bearing, balls between the bearings, a wick which eX- tends through the bolster and into the oilchamber, a whirl having interiorly a sleeve or skein between the bearings on the bolster, and externally a pulley between the bearings; together with a spindle which is carried by the upper end of the whirl, substantially as shown.

6. In a spindle-support, the combination of a support having an oil-chamber, a recess in the upper portion of the support, an oil-cup in the exterior of the support, a passage which connects the recess with the oil-chamber and with the oil-cup, a hollow spindle connected to the support, bearings on the spindle, oilducts through the spindle for leading oil to the bearings, a whirl, the lower portion of which extends into the recess in the upper portion of the support, a spindle carried by lthe upper end of the whirl, bearings remov- TIGSSGS.
